ICP: Silence objtool "stack pointer realignment" warnings
Objtool requires the use of a DRAP register while aligning the
stack. Since a DRAP register is a gcc concept and we are
notoriously low on registers in the crypto code, it's not worth
the effort to mimic gcc generated stack realignment.

We simply silence the warning by adding the offending object files
to OBJECT_FILES_NON_STANDARD.
